We focus on petroleum refining, environmental protection, chemical technology application & R&D, as well as project design, equipment manufacturing and sales. With in-depth cooperation with Sinopec Shanghai Research Institute and Nanjing Chemical Research Institute, we maintain industry-leading technology advantages.
Our key technologies include waste engine oil regeneration (oil-gas phase directed catalytic cracking), tire oil separation (gasoline/diesel meet national standards), new-type base oil refining, crude oil/waste engine oil hydrogenation (producing Euro-standard oil & API-certified Group II/III base oil), etc. Adhering to "Technology First, Quality First", each technology/equipment undergoes strict calculation and simulation tests, supported by professional software like Aspen, Pro2 and CAD.
